Project description:Transcriptional profiling to identify genes differentially regulated by stromal specific Ptch1-deficiency during embryonic kidney development. Ptch1 was specifically deleted from stromal progenitors using Foxd1-driven Cre recombinase
Project description:Purpose: To analyze the mRNA content of Foxd1Cre;Smo(flox/-) mutant kidneys. Methods: We collected E13.5 wildtype and Foxd1Cre;Smo(flox/-) mutant kidneys and isolated RNA to do RNA-Seq. Results: Identified differentially expressed transcripts in Foxd1Cre;Smo(flox/-) mutant kidneys compared to wildtype controls. Conclusions: Our work provides novel insight into how Hedgehog signaling from stromal cells influences renal development.
Project description:Transcriptional profiling of cultured CD1 mouse embryonic kidneys (E13.5) comparing HDACi-treated kidneys with control drug-treated kidneys. Studies in our lab showed that pharmacological inhibition of HDAC activity in ex-vivo cultured metanephroi results in extensive defects in kidney development, including impaired UB branching, tubulogenesis, and glomerulogenesis, accompanied by cell cycle arrest and apoptosis.The goal of the microarray analysis was to elucidate the morphogenetic pathways affected by HDACi. Two-condition experiment, HDACi-treated E13.5 kidneys (Scriptaid 2.0 μg/ml x 6hrs) vs. Control drug-treated E13.5 kidneys (Nullscript 2.0 μg/ml x 6hrs). Biological replicates: 3 control replicates, 3 HDACi-treated replicates. Two-color Agilent 4x44k chips with dye-swap on 2 of 4 arrays.
Project description:Transcriptional profiling of mouse embryonic kidneys (E13.5) comparing UB HDAC1,2-/- kidneys with wild type kidneys. Studies in our lab showed that histone deacetylase 1 (HDAC1) and 2 (HDAC2) perform redundant, yet essential functions in the developing mouse ureteric bud (UB) tissue. Double deletion of HDAC1 and HDAC2 in the UB results in impaired UB branching morphogenesis, followed by severe kidney dysgenesis. The goal of the microarray analysis was to identify the genetic pathways controlled by HDAC1 and 2 in the UB. Two-condition experiment: E13.5 mutant kidneys (UB HDAC1,2-/-) vs. E13.5 wild type kidneys . Biological replicates: 4 control replicates, 4 UB HDAC1,2-/- replicates. Two-color Agilent 4x44k chips with dye-swaps on 2 of 4 arrays.

Project description:We have employed whole genome microarray expression profiling to identify genes regulated by Sall1 in the kidney. Kidneys at E13.5 were obtained from inducible Sall1 deletion 24 hrs after tamoxifen treatment (2 set).
Project description:In mammals, gonadal differentiation is the first step of sex determination, and the transcription factor Sox9 promotes testis differentiation. Here we used the XY Sox9flox/flox; Sf1:creTr/+ mouse model and show that the lack of Sox9 expression induces a full sex reversal of E13.5 XY Sox9flox/flox; Sf1:creTr/+ gonads compared to XY Sox9flox/flox. Keywords: gonads gene expression profiling in WT and Sox9flox/flox; Sf1:creTr/+ mice 3 WT versus 3 Sox9flox/flox; Sf1:creTr/+ mice.
